[PATCH v3 2/3] Documentation/process: maintainer-soc: add clean platforms profile

[Krzysztof Kozlowski]

Some SoC platforms require that commits must not bring any new
dtbs_check warnings.  Maintainers of such platforms usually have some
automation set, so any new warning will be spotted sooner or later.
Worst case: they run the tests themselves.  Document requirements for
such platforms, so contributors can expect their patches being dropped
or ignored, if they bring new warnings for existing boards.

Changes in v3:
1. Rephrase according to Rob's comments (this document when referenced
   in maintainers, "... and dtc Compliance", existing warnings are not
   new warnings).

Changes in v2:
1. Add Rb tag.
2. Implement Conor's feedback: change doc title, follow->should follow,
   minor style changes.

+==============================================
+SoC Platforms with DTS Compliance Requirements
+==============================================
+
+Overview
+--------
+
+SoC platforms or subarchitectures should follow all the rules from
+Documentation/process/maintainer-soc.rst.  This document referenced in
+MAINTAINERS impose additional requirements listed below.
+
+Strict DTS DT Schema and dtc Compliance
+---------------------------------------
+
+No changes to the SoC platform Devicetree sources (DTS files) should introduce
+new ``make dtbs_check W=1`` warnings.  Warnings in a new board DTS, which are
+results of issues in an included DTSI file, are considered existing, not new
+warnings.  The platform maintainers have automation in place which should point
+out any new warnings.
+
+If a commit introducing new warnings gets accepted somehow, the resulting
+issues shall be fixed in reasonable time (e.g. within one release) or the
+commit reverted.

[PATCH v3 3/3] MAINTAINER: samsung: document dtbs_check requirement for Samsung

[Krzysztof Kozlowski]

Samsung ARM/ARM64 SoCs (including legacy S3C64xx and S5PV210) are also
expected not to bring any new dtbs_check warnings.  In fact this have
been already enforced and tested since few release.
